User interface providing method using pressure input and electronic device implementing same

An electronic device comprising:

• a housing comprising a first surface facing a first direction, and a second surface facing a second direction opposite the first direction;
• a display arranged between the first surface and the second surface, and exposed through the first surface;
• a touch sensor arranged between the first surface and the second surface, and configured to detect a point of at least one touch by an external object on the display;
• a force sensor arranged between the first surface and the second surface, and configured to detect a force applied against the display by the external object;
• at least one processor electrically connected with the display, the touch sensor, and the force sensor;
• and
• a memory electrically connected with the processor and configured to store a plurality of application programs comprising a plurality of functions, respectively,
• wherein the memory is configured to store instructions that, when executed, cause the at least one processor to:
• display a user interface on the display,
• receive, from the touch sensor, first data indicating that the external object touches a part of the display,
• receive, from the force sensor, second data indicating a force applied against the display by the external object while the external object is touching a part of the display,
• determine at least one application based at least in part on the first data,
• determine a change of a direction of the force applied against the display by the external object, based on at least part of the first data or the second data, the direction being perpendicular to the first direction,
• select a function associated with the at least one application based on at least part of the change, and
• perform the selected function.
